Rules for Sun Umbrella Purchase
1. When choosing an umbrella surface, umbrellas with obviously sparse fabrics generally have poor UV resistance, so consumers should buy them carefully.
2. Because the fabric has the characteristic of shrinking, when buying a parasol, the surface of the umbrella should be large rather than small.
3. The color of the fabric is related to the UV protection performance. Under the same conditions, the darker the fabric, the better the UV resistance. In contrast, black, navy blue, dark green and light blue, light pink, and light yellow have better UV resistance.
4. Check the protection grade mark carefully before purchasing. The “Assessment of Textile Anti-UV Performance” promulgated by the General Administration of Quality Supervision, Inspection and Quarantine stipulates that only when the UPF (ultraviolet protection factor value) is greater than 30 and the UVA (long-wave ultraviolet) transmittance is less than 5%, it can be called an anti-ultraviolet product. The standard is “UPF30+”; when the UPF is greater than 50, it indicates that the product has excellent UV protection performance, and the protection level is marked as “UPF50+”. Consumers should carefully check the protection level signs when purchasing, and then choose the umbrella that suits them according to the local sun exposure.
5. Choose brand-name products and beware of counterfeit anti-ultraviolet umbrellas.
6. The anti-ultraviolet performance can be preliminarily judged according to the fabric properties of the umbrella surface. Generally speaking, cotton, silk, nylon, viscose, etc. have poor UV resistance, while polyester is better. Polyester-containing fabrics usually used to make umbrellas include satin cloth, mac cloth, etc. In addition, the anti-ultraviolet performance is best for satin weave fabrics, followed by twill weave and plain weave, the darker the better.
7. Whether the sunscreen umbrella can protect against ultraviolet rays, the texture of the fabric is not the most important thing. The main thing is what kind of technical treatment the manufacturer has done to the fabric. Generally, cotton and linen fabrics have a certain degree of UV protection, but the degree is not strong.
Most of the sunscreen umbrellas sold on the market in the past two years are coated with a layer of silver glue on the umbrella surface. This treatment can reflect and block some direct ultraviolet rays. However, the quality of silver glue is good or bad. The silver glue of sunscreen umbrellas produced by manufacturers with good technical conditions is not easy to fall off, and some cheap sunscreen umbrellas just coat the surface of the umbrella with a layer of silver in order to refill the number. After several sun exposures It faded.
8. When the umbrella surface is wet, due to the optical transmission of water, the transmittance of ultraviolet rays increases and the protective effect decreases. Therefore, wet umbrellas are not suitable for UV protection
